Mark Perry at Foreign Policy has uncovered a juicy story about how members of Israel's intelligence agency posed as American spies to recruit terrorists in Iran.

Buried deep in the archives of America's intelligence services are a series of memos, written during the last years of President George W. Bush's administration, that describe how Israeli Mossad officers recruited operatives belonging to the terrorist group Jundallah by passing themselves off as American agents. According to two U.S. intelligence officials, the Israelis, flush with American dollars and toting U.S. passports, posed as CIA officers in recruiting Jundallah operatives -- what is commonly referred to as a "false flag" operation.

The memos, as described by the sources, one of whom has read them and another who is intimately familiar with the case, investigated and debunked reports from 2007 and 2008 accusing the CIA, at the direction of the White House, of covertly supporting Jundallah -- a Pakistan-based Sunni extremist organization. Jundallah, according to the U.S. government and published reports, is responsible for assassinating Iranian government officials and killing Iranian women and children.

But while the memos show that the United States had barred even the most incidental contact with Jundallah, according to both intelligence officers, the same was not true for Israel's Mossad. The memos also detail CIA field reports saying that Israel's recruiting activities occurred under the nose of U.S. intelligence officers, most notably in London, the capital of one of Israel's ostensible allies, where Mossad officers posing as CIA operatives met with Jundallah officials.

The officials did not know whether the Israeli program to recruit and use Jundallah is ongoing. Nevertheless, they were stunned by the brazenness of the Mossad's efforts.

"It's amazing what the Israelis thought they could get away with," the intelligence officer said. "Their recruitment activities were nearly in the open. They apparently didn't give a damn what we thought."

There is little doubt Jundallah is a terrorist organization. The State Department has them on their list of terrorist groups, as do our NATO allies. There have been a few realists in the foreign policy community who have urged the US government to utilize and support Jundallah, claiming they aren't really terrorists, but freedom fighters. It's a weak case considering the list of attacks the terrorist group has carried out -- many of which killed innocents.

But Mossad is in an entirely different position than the US. Iran is an existential threat and working with the raw material at hand - even if that raw material is considered a terrorist outfit - seems justified under the circumstances.
